The linker sees it the BFD way, objdump sees it the BFD way, - GAS sees it the BFD way. There was need for a tool to go find out what - the file actually says. - - This is why the readelf program does not link against the BFD library - it - exists as an independent program to help verify the correct working of BFD. - - There is also the case that readelf can provide more information about an - ELF file than is provided by objdump. In particular it can display DWARF - debugging information which (at the moment) objdump cannot. */ - -#include <assert.h> -#include <sys/types.h> -#include <sys/stat.h> -#include <stdio.h> -#include <time.h> - -#if __GNUC__ >= 2 -/* Define BFD64 here, even if our default architecture is 32 bit ELF - as this will allow us to read in and parse 64bit and 32bit ELF files. - Only do this if we believe that the compiler can support a 64 bit - data type.
